Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Pairs of parallel horizontal wells, one for steam and one for production, make it possible to recover bitumen continuously from oil sands. Energy and Capital editor Keith Kohl discusses 3 oil investments that are booming from record oil prices. Improving Energy Efficiency in Thermal Oil Recovery. There has been an increase in the exploration of unconventional crude oils, which almost equal global conventional oil reserves - from bitumen through to heavy oils. Ivanhoe Energy The crude gravity is similar to Athabasca bitumen, at approximately 8° API, however other characteristics are quite different and present specific upgrading challenges. The prize Royal Dutch is chasing is The firm is trying to commercialize what it calls a "novel thermal recovery process" invented by Shell's technology arm. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. Kerogen in oil shale is a solid that is either The ultra-heavy oils are recovered in situ by heat injection, mostly as steam. Improving Energy Efficiency in Thermal Oil Recovery Surface FacilitiesN.M. Zones too thin for traditional thermal recovery. Solid tar sand bitumen is mined and liquified in surface plants. The company, through a secretive Calgary-based subsidiary called Sure Northern Energy Ltd., is working to unlock an estimated 60 billion barrels of raw bitumen — more than 100 kilometres west of the oil sands epicentre around Fort McMurray in northeastern Alberta. However, the random nature of the carbonate bed, which is neither uniform nor consistent, makes economical bitumen recovery a technological challenge. ET Energy's Electro Thermal technology could be used to pump out 600 billion barrels of Alberta's oil sands bitumen. One of the problems is that the current extraction Some these methods include thermal recovery, as well as chemical or gas injection. There are currently two main categories of processes for in situ—i.e., underground, without mining—thermal recovery of bitumen and heavy oil: steam injection and combustion. Ivanhoe Energy's goals for the initial wells in Pungarayacu were to add to its preliminary understanding of the reservoir, to carry out thermal recovery tests, and to extract heavy oil for characterization and upgrading tests using its proprietary HTL upgrading process. Only 20% of the total amount of recoverable bitumen (the thick, tar-like form of petroleum) can be done through surface mining, leaving an overwhelming amount that will be extracted from In-Situ methods.
